<p>My understanding is that the petid chips require the reader to be too
close to be functional for this purpose. </p>
<p>Maybe rfid tags on their collars (if they allow themselves to be
collared). </p>
<p>Here is a discussion of this, with two instructable links, and once on
instructables, there are some additional links to similar projects. </p>

<p>I like this one for the ability to dispense smaller quantities of food. <br>

You could combine that with an rfid reading system. I don't know about your
cats, but mine tend to only eat about 4 kibble at a time, so the machine
would have to acknowledge which cat it was and add the 4 kibble to that
cat's counter. Obviously, a distribution of food that doesn't leave them
eating all their kibble before 9am would also be ideal. </p>
<p>I really like this project, and am living vicariously through you
because my girlfriend isn't willing to let the cats' food be dependent on a
robot that I've built. Come on out to a modlab night, and we
can brainstorm this further. </p>

I haven't
looked into that yet but the recent 5am foody calls are starting to
motivate me to find an automated solution. I would need a per/cat solution
as one of them tends to overeat. I wonder if I could have a set of three
gates--each unlocked by their pet ID chips.</div>

Thanks for the
clarification on in the intended audience. I'll keep watching the list
for any workshops that are suited to my level.</div>

Anything that helps us to serve our feline overlords would be of use.
Aside from that, I've been thinking of making a persistence-of-vision

Thank you everybody who is interested in this workshop. When Darcy and I
were talking, we envisioned that this first course was going to be a truly
beginner's workshop. If you've run blink on an Arduino, you might
already be too advanced. If you've built any other project on an
Arduino, you're definately too advanced.<br>

<br>
Your interest is exciting though, it tells us that our thoughts might be
along the right lines. We already have ideas for future workshops that
will build upon what this one teaches, and those *will* be suitable for
someone who has run blink or their own simple project before.<br>
